Title: Malfunction detector for mechanical facility
Inventor: HIRATA KINGO
IPC: G01M99/00
Filed: 1978-07-27
Abstract: PURPOSE: To automatically warn only a malfunction by using a frequency and an amplitude as such a variable as quantitatively evaluates the mechanism vibrations.  
     CONSTITUTION: The value α of a variable attenuator 3 is so adjusted that the output E out  of a subtraction absolute value circuit 11 thereby to equalize the outputs of rectifying smoothening circuits 6 and 7. Mechanical vibrations are varied so that the output of a sensor 1 has its high frequency component of K 1  and VH and its low frequency of K 2  and VL. For K 1 VH>K 2 VL, the gain of an AC amplifier 2 becomes higher in response to AGC signals, and the output of a sector 8 is varied to become a standard voltage E s . As a result, a relationship of E out =E s (1-K 2 /K 1 ) is obtained so that the output E out  relates to the ratio of the mean levels of the high and low frequency components. If, therefore, the set value EL of a variable setter 13 is suitable set in accordance with the importance of an object machine and experiences, a relay circuit 12 acts when the output E out  exceeds the value EL. Thus, a warning signal for the abnormal condition of the mechanical facilities can be automatically generated.
